T l wiwm i m y n rn: axle, and close to the box d is a flan e or Be it known that 1, JOHN Onius'rorn MAU- guard f, whereby is prevented the possi )ility RE'B a citizen of the United States, residing of the string, being caught and'wound into in hicago, Illinois, have invented certain the axle end or box by careless unreeling of 5 new and useful Improvements in Gyroscopes, the strin Only one axial or adjusting of which the following is a specification. screw is s own in Fig. 1. The box (1 at the My invention relates to improvements in opposite end may be fastened to the axlegyroscopes' in which an adjusting screw or ring i in an known or convenient way which screws axially coincident with the axis of the for general purposes is sullicient. The screw \0 wheel boxes provided with ballbcaror screws 6 work tightly through the ring t.

The combination with a rigidly-united The wheel, consisting of the parts a b g and wheel, axle and axle-flange, of an axle-ring,
